    Types This section provides a brief explanation of the supported RAID configurations for HP Compaq dc7800 Business PCs. RAID 0 with two hard drives (Striped) Even though HP supports RAID 0, it is not the recommended configuration for business PC users. Lack of redundancy causes less than half the

    hard drives At a higher reliability cost with faster performance, the HP Compaq dc7800 Business PC Convertible Minitower also allows for RAID 0 with three hard drives. RAID 0 with two or three hard drives is a supported configuration. RAID 0 with three hard drives is shown in the following figure

    proposition, RAID 1 is the only RAID configuration that HP preconfigures for HP Compaq dc7800 Business PCs. RAID 1 provides RAID 1 has redundancy and hence is a true RAID. It more than doubles reliability because the MTBF of RAID 1 is equal to the MTBF of an individual drive multiplied by the number
